931 Signal Conditioners
Our Bulletin 931N Nano and 931S Smart signal conditioners provide a full range of options to isolate, convert, split, linearize, and amplify a broad range of signal types.
937C Converter Barriers
Our Bulletin 937C Converter Barriers add functionality to the isolators by receiving signals from a hazardous area instrument i.e., temperature sensors, or load cells, and then converting them to an industry standardized signal such as 0/4…20mA or 0/2…10V.
937T Isolator Barriers
Our 937T Isolator Barriers include galvanic optical or transformer isolation, these modules provide an interface within the intrinsic safety circuit that is electrically separated from the control system.
937Z Zener Barriers
Our Bulletin 937Z Zener Barriers provide protection for electrical signals within hazardous areas. These barriers feature a narrow profile of just 12.5 mm to maximize control panel space.
